Revealing Nafion‐Induced Copper Modifications by Combining In Situ and Ex Situ X‐Ray Absorption Spectroscopy

open access: yesSmall, EarlyView.
This work elucidates that Nafion alters Cu‐based CO2RR catalysts by promoting partial Cu dissolution and stabilizing Cu2+ species through coordination with sulfonate (‐SO3−) groups. Combining in situ Cu L‐edge with ex situ Cu K‐edge XAS measurements, the study highlights how Nafion primarily modifies the nanoparticle surface, while less oxidized Cu ...

Voter Access under Mandatory Voter ID: The Promise and Limits of the Voter Authority Certificate

open access: yesThe Political Quarterly, EarlyView.
Abstract The Elections Act 2022 introduced mandatory photographic voter identification in UK general elections and English devolved elections, marking a decisive shift toward a universal requirement for in‐person voting. To mitigate access barriers in the absence of a national identity system, it also provided for the introduction of a new Voter ...
